Yay! Readers finally arrived, cobbled them together, and magically got something to work without frying the chip. Also this is great because I can directly flash the SAGE if I brick it.

Link is for a dump of the Project Olympus/Open Computer motherboard (https://www.opencompute.org/wiki/Server/ProjectOlympus)

@Lost_N_BIOS All up to you!

So I used MC Extractor to check the differences. I can see the cpuid/platform from the M$ bios is the same as Lost's modded bios, I am not sure if the revision/size/offset/last need to be adjusted.

I am still unable to get the physical server to boot into something I can use. So that adds a bit of a hiccup.

@xurious - BIOS link = 404 Please re-up, thanks
Can you boot to BIOS with the Olympus and these CPU's, or no? If no, what about booting that server with other retail CPU's you have?
I can make you a BIOS for SAGE with all those older microcodes if you want, it probably wont make a difference but is worth trying

"Last" just means is this latest version or not. Generally, all these ES are 50650-50653, maybe a few ES 50654, but 50654-50657 = retail
This is one of the reasons I wanted to see that BIOS, to see which ES microcodes were in there, and additionally why I wanted to see this board boot with those CPU's, so we could confirm if the BIOS boots the CPU and or what CPUID the CPU actually is.
As it looks, unless this CPU is some rare ES of 50654-50657, that board should not boot this CPU

Hm, odd. Here it is again: https://file.io/oyCCLLondqL6

I can not get the servers to boot under any condition I've tried. I've tested a few of them. If you believe changing the BIOS won't work, then no need to make a mod at the moment. I'll need to look into another avenue.

Good idea on tossing the known working CPUs into the olympus chassis.

Ah. That explains that. Tinyupload isn't working across 3 pcs and a handful of browsers.

This will nix the problem for now: https://drive.google.com/file/d/1STzy1Z0...iew?usp=sharing

@xurious - Yes, tinyupload has been failing on uploads for a few days now, this happens sometimes
Should you be able to boot server to BIOS? I assume so, but I've never used any server, so not sure how they work. Yes, it would be great if you have some other retail CPU to try here, any with CPUID 50654-50657 should work
Do these boards have a debug LED onboard? If yes, what codes do you see, and what does it stop on? Have you tested with single CPU and one stick of memory, have you tested different sets of memory?
If they do not have debug LED, do you have a PCI debug POST card, if these have a PCI slot to use one in?
It would be great if we at least knew these CPU'd CPUID, but at least we know the mod BIOS covers all other known ES, so these should boot too based on all the others being OK, they could possibly be faulty unless they do need some old microcode for some reason.
I will make you SAGE BIOS with the same microcodes as this server tonight

I assume the server is posting, but there is no onboard video and the dedicated pcie gpu does not present video.

There is uart debugging headers, but I don't have the tooling/skills for that.

The ideal way to access it would be through the onboard BMC. At present I can not get it to request an IP address and don't know the default or current ip.

The only onboard debug led just stays red at the moment. I've done the standard of ensuring all items are fully seated. I also don't have a debug pcie card, may be time to finally acquire one.

I know these servers ran windows hyperV with the standard windows sever GUI, I can take the main ssd and boot it in another server.

One thing I have not tried is adding a standard pcie nic, booting a debian live image, and seeing if it pulls dhcp from there.

I don't have any retail chips, but I will try with the other ES ones.

@xurious - You can't assume it's booting past POST Especially if you can't get any visual output << Did you try a few PCIE cards, removing the original? Or can you not use standard PCIE Card, I can't tell from the single image at the link above.
Can you ping it, or see if from a router? Debug LED = Red? So it's not alphanumeric?
Yes, if there is PCI slot, get a $3 PCI Debug post card, it will let us know if stalling or posting etc.
So, you can't get into it's BIOS?

@Lost_N_BIOS Hi again, finally had the chance to flash your latest mod bios. But I'm getting stuck on code 66 with 1 long and 3 short beeps with it. QL1K ES CPU Platinum 8160 <- with those cpus.
Gonna flash back to the old bios and see if it goes back to rock solid again.

EDIT: Ok, after flashing back to the old bios (working fine) and then flashing back to the new one again it started working as supposed. Might have been some extra hw that I removed between the first flash and the second that did the trick.
So it seems to be all good! Sweet work as usual! ;)

Thanks alot!

@Babar - Not 100% sure what 66/bb error and those beeps mean, but maybe this is a memory or settings issue, did you try to clear CMOS?
QL1K confirmed working with latest 6201 mod BIOS already by @levelud here at post #407-409 levelud what is your CPU models, same 8160's?

Yes, confirmed on page 2-3, error 66 1 long and two short beeps (no one mentions 3 short beeps, so assume it's two?) is a memory related error (no memory specifically). May also be PXE Init, but still memory related.
I see one long and three short is VGA issue, in the SAGE manual. Did you test with single socket CPU and one stick of memory? Did you try other memory, just as testing?

Ahh, just edited my post before refreshing to see your reply.. Anyway, all good now! :)
And yeah, it might have been a vga issue, because I'm running 3 gpus off the first pcie slot using bifurcation, and I removed those before the second try.

@Babar - Great to see you got it going!! 3 GPU's via bifurcation, wow!
Nice it's working for you now

Jupp, the plan is more gpus, just need the cash ;)
Maybe now that ppl are dumping gpus for the new 3000 series nvidias..

Folks, I want to start by saying a big thanks to everyone who started and is maintaining this project. I specifically built my system around the C621e because of reading this thread and realizing the value of being able to use B0 stepped chips. Glad to say I finally built the system today, flashed the BIOS and was able to boot without errors. You've created an incredible source of value for the community, thank you!

Quick newbie follow-up that I couldn't find answer to in the thread: I can't seem to get the multiplier on my 2 QL1K's to go above 22 (on the 10-32x scale). Am I missing something? I set the BIOS to both "Core Optimizer" and "Engine Boost" and while it does max the CPU to a constant 22x, it still won't go beyond that point.
